Straightening small Copper pipes.

[Tony Bird]

Hi,

I hope this is found interesting. Following is how I straighten small diameter copper pipes.

First anneal.



Then roughly straighten.



Put one end in a vice and pull the other end with a pair of pliers.



End result.




Regards Tony.

I do that with wire at work all the time. Not sure I would have tried it on tubing. Good thinking.

Hi Steve,

When I was gainfully employed we used to hand draw wire annealing about every third pull and it was years before I thought of straightening pipes the same way. But like wire it works better with longer rather than shorter lengths.

Regards Tony.

Galvanised steel wire comes in coils. Manual uncoiled them and straightening them hammering on a flat surface was slow and results never good.
Watched my next door uncles straightening 1/8 G.I. Steel Wire in the 1950s. With one end clamped in a vise and the other end pulled and clamped in hand drill chuck . After about a hundred rounds wire was straightened. Results very good and that is if you can accept wire twisted straight.
Gus had a team making wire net belt guards for air compressors. We use Taiwanese wire straightening/uncoiling machines. Very straight and cut to exact length by fly cutter. Just in 5 minutes we had a couple of hundred wires done.
